Free Tools for WhatsApp and AI Support
A collection of free tools to help businesses get more from WhatsApp Business API, automate customer support, and measure ROI. No sign-up required.
These free utilities are built to help sales, marketing, and support teams optimize their communication setup. Use them to estimate WhatsApp API costs, calculate chatbot ROI, benchmark team performance, and generate compliant Meta message templates instantly.
Why these tools cost nothing
Each of these started as something the Dunefox team built to answer a question we kept getting from prospective customers: what will WhatsApp API actually cost, is a template going to get rejected, would an AI chatbot even pay for itself. Turning the internal version into a public tool takes a day and helps anyone evaluating WhatsApp automation, whether or not they ever sign up for Dunefox.
No account, no email, no usage limit. Everything runs in your browser, nothing you type into a calculator or the template builder is sent to us or stored anywhere.
Which tool for which job
If you already have a WhatsApp Business API number, start with the pricing calculator, it turns your monthly conversation volume into a real cost estimate using Meta's own rates. Setting up your first automated message, the template generator gets you a Meta-ready template with variables and buttons in a couple of minutes.
Still deciding whether AI support is worth the switch, the chatbot ROI estimator and response time calculator turn your current ticket volume and agent costs into a payback estimate you can take to whoever signs off on the budget.
Frequently asked questions about Dunefox
Are these WhatsApp tools actually free, or is there a catch?
They are free with no catch. No sign-up, no card, no usage cap. Dunefox builds these as a genuine resource for anyone running a WhatsApp Business API setup, whether or not they ever become a Dunefox customer. The business reason is straightforward: a business owner who uses the pricing calculator or link generator today is a plausible Dunefox trial signup next quarter, so it costs us little to give the tool away in full.
Do I need a WhatsApp Business API account to use these?
It depends on the tool. The WhatsApp link and QR generator works with any WhatsApp number, personal or business, no API account needed. The API pricing calculator, message template generator, and chatbot ROI estimator are built around WhatsApp Business API concepts (conversation categories, template approval, Meta pricing) and are most useful if you already have, or are evaluating, an API account. None of them require you to connect an account to use the tool itself.
Is my data saved or sent anywhere when I use these tools?
No. Every tool on this page runs entirely in your browser. Numbers you enter into the pricing or ROI calculators, or text you type into the template generator, are not transmitted to Dunefox or stored anywhere. Closing the tab clears everything.
What is the difference between the template generator here and templates in the Dunefox app?
This generator builds the JSON payload and preview for a single WhatsApp template, which you can copy and submit to Meta Business Manager yourself through any BSP. Inside the Dunefox app, template creation is connected to your actual WhatsApp Business account: submission, approval tracking, and sending the approved template to a segmented audience all happen in one place, with an AI assistant that can draft the template from a plain-language description.
How accurate is the WhatsApp API pricing calculator?
It uses Meta's officially published per-conversation rates by category and country, the same rates any WhatsApp Business Solution Provider bills against. Your actual invoice may differ slightly if your provider adds its own markup on top of Meta's rate. Dunefox does not add a markup on Meta's conversation fees.
Can I use these tools if I am not a Dunefox customer?
Yes. There is no requirement to sign up for Dunefox, now or later, to use any tool on this page. If a tool turns out to be useful enough that you want the fuller version, the 14-day free trial link on each page gets you into the app with no card required.
